Found this cool widget (I think that’s what its called):
http://www.dinceraydin.com/djlcdsim/djlcdsim.html
It’s an LCD simulator! Can be handy if you don’t have the real thing to play with… or forgot to get new batteries >.

Does anyone else find this voltage combination a bit… fishy?
I can understand designing a board that can run off of both 3.3V and 5V logic, where the supply voltage range is 3.0 to 7.0V and the I/O can accept the same range.
I don’t know, for some reason I keep thinking that if your I/O voltages are higher than your supply voltage you’ll end up with a current backflow through the supply pins.

Out of curiosity, what is the reccomended samping rate for this board?
From looking at the schematic (and referring to the supplied datasheets), I see that the Gyro’s have a -3dB LPF at around 48Hz and the Accelerometers have a -3dB LPF at 50Hz.
I’m currently running the ADC at a rate of 110Hz, and I’m worried that I might be sapping some performance and/or introducing noise…

It’s one of several different coordinate schemes:
This board has the X and Y angle set up so that a positive X angle tilt will result in a positive linear acceleration (and displacement) along the X axis, and a positive Y angle tilt will result in a positive acceration along the Y axis.
It seems like this was more intended for quadrotors and helicopters than for airplanes and other craft.

Have you tried using a file or serrated knife to first score along where you want to break it? An old butterknife might do the trick.
Once you’ve scored it, use a pair of pliers to quickly twist the wanted pins off the row.
*Note: I haven’t tried this technique on plastic, but it works well with copper-clad board

In 2003, CU student Nate Seidle blew a power supply in his dorm room and, in lieu of a way to order easy replacements, decided to start his own company. Since then, SparkFun has been committed to sustainably helping our world achieve electronics literacy from our headquarters in Boulder, Colorado.
